| Abstract: |
Differential thermal analysis DTA at different heating rates for Ge(10+x) Se40 Te(50-x) chalcogenide glasses are reported and discussed. characteristic temperatures Tg, Tc and Tm were estimated at different heating rates. Cyclic scanning technique was used to investigate thermal induced phases during two consecutive heating-cooring cycles covering the temperature range Tg- Tc. The effective activation energy (E), the order (n) and the rate (k) of crystallization, along with the growth (m) under non-isothermal conditions are also reported. Obtained results were treated according to Johnson- MehI- Avrami and modified kissinger approaches. |
